Abstract
Description
- This is a continuing application, under 35 U.S.C. § 120, of copending international application No. PCT/EP/2006/009143, filed Sep. 20, 2006, which designated the United States; this application also claims the priority, under 35 U.S.C. § 119, of German patent application No.
DE 10 2005 045 453.4, filed Sep. 22, 2005; the prior applications are herewith incorporated by reference in their entirety. - 1. Field of the Invention
- The invention relates to a service ceiling, in particular for laboratories, and to a method of installing such a ceiling. The service ceiling routes supply lines in a room of a building, in particular a laboratory, having at least one aisle region. The service ceiling contains an intrinsically rigid carrier frame composed of profiled members which is fastened in the region of the ceiling of the room, and also at least one air inlet duct for feeding in fresh air, along with lines for feeding in sanitary media.
- When setting up research laboratories for chemical or physical research, for example, it is known practice in the building industry to employ ceiling constructions in which the feed lines for exhaust air, inlet air, the technical gases required in the laboratory, and liquids, and power and data lines, etc., within the ceilings are fastened directly to the associated building ceiling with the aid of suitable fastening devices by use of dowels. Since these lines are generally laid successively by different personnel, the problem arises that not only do the lines sometimes extend in a crisscross and alternating fashion in a number of planes, but also that, in addition, because of the individual mounting of the fastening devices, any spatial modifications to an existing laboratory arrangement can only be made with a great deal of effort.
- It is accordingly an object of the invention to provide a service ceiling, in particular for laboratories, and a method of installing such a ceiling that overcomes the above-mentioned disadvantages of the prior art devices and methods of this general type, which enables the various feed lines to extend in a structured and ordered manner and which can additionally be subsequently adapted to a modified laboratory structure in a flexible manner. A further object of the invention is to provide a method whereby a service ceiling can be installed in a simple and cost-effective manner.
- With the foregoing and other objects in view there is provided, in accordance with the invention, a service ceiling for routing supply lines in a room of a building such as a laboratory, the room having at least one aisle region. The service ceiling containing an intrinsically rigid carrier frame composed of profiled members, having an underside, and fastened to a region of a ceiling of the room, the intrinsically rigid carrier frame extending in a first plane at a distance from the ceiling of the building. At least one air inlet duct for feeding in fresh air is provided. The air inlet duct extends above the aisle region substantially flush with the underside of the instrinsically rigid carrier frame, in a plane of the intrincially rigid carrier frame. Lines for feeding in sanitary media are provided, the lines extend above the air inlet duct in a second plane.
- According to the invention, a service ceiling serves as a horizontal room division, and contains all the integrated service components such as inlet air and exhaust air, power, light, gases, water, communications, etc. The service ceiling is suitable for building new laboratories and converting existing ones, and also for production and research plants and training facilities, in particular for the chemical and pharmaceutical industries.
- The service ceiling preferably contains a flexurally rigid system of metal profiles which is configured in its cross section or height in such a way that the air inlet and exhaust duct, busbar, electrical duct, the media supply and the light can be arranged within the service ceiling without crossing. The carrier frame or the basic grid of the service ceiling contains profiled members, made up in particular of primary members, secondary members and ceiling columns. The primary members are divided into central members and edge members. The central members are twice as wide as the edge members. The central members are preferably situated centrally above the central tables of the laboratory.
- The ceiling columns serve as connection elements between the building ceiling and service ceiling.
- It is possible for a plurality of service ceilings in the form of modules to be installed in a room, with the individual service ceilings of a room being connected to one another by the joined-together edge members. These two edge members together likewise produce a primary member or central member. The service ceiling can be mounted at any desired height.
- The air inlet duct is located centrally in the direction of the central aisle between table and/or fume hood workstations.
- The exhaust air duct is located parallel to and alongside the edge members.
- The lines used to route the various media are arranged, in particular in a U-shape, on the service ceiling and are located centrally above the air inlet duct.
- The media columns can be tapped by way of the supply points which are located centrally over the air inlet duct for each quadrant of a laboratory. The supply points are of modular design and can be adapted for each medium that is required. The components of the media connecting points are preferably constructed inline with through-connecting adaptors.
- The media columns can be mounted on the carrier system and are displaceable.
- The fact that the supply points are located in each quadrant of a laboratory results in that the room can be divided up a number of times by use of partition walls. The flow of inlet air can be routed separately into each divided laboratory section via associated volumetric flow regulators.
- The busbar and the electrical duct preferably extend parallel to the media.
- Shelf units can be mounted on the central members and edge members.
- Partition walls can be mounted below the central, edge and secondary members.

By virtue of the high cross section of the service ceiling, the lamp type can be chosen freely. The lamps can be displaced longitudinally and transversely with respect to the primary members.
- The air inlet duct is configured in such a way that the outlet openings can be disposed to be closable. The entire service ceiling can be closed downwardly by ceiling panels of various colors and materials. It is also possible in this connection for there to be provided, below the outlet openings of the inlet duct or ducts, baffle plates having a multitude of holes whose diameter is smaller than that of the outlet openings, in order to produce a laminar planar flow of inlet air.
- The connections with the main, secondary, axial and edge members are preferably made in a flexurally rigid manner and are preferably grounded.
- Furthermore, mechanical securing devices can be installed in the ceiling columns, these devices securing the main members against dropping down should the associated fastening device loosen in the course of time.
- All accessories such as, for example, known T-shaped slot nuts and threaded plates can be used in all the secondary and main members.
- The service ceiling has a high degree of flexibility, is maintenance-friendly, shortens the installation time and reduces costs, since all the connections, ducts and supply lines can be planned uniformly in advance.
- The surface nature of the members matches the laboratory surroundings. It is advantageous in this respect if this also applies to the beginning or end of the profiles in order to prevent the outer coating of the members from peeling or flaking when the members are cut to length.
- In accordance with an added feature of the invention, a further air inlet duct extends above a further aisle region within the plane of the intrinsically rigid carrier frame, the lines for feeding in the sanitary media in the second plane are routed parallel to one another in a form of a U from the air inlet duct to the further air inlet duct, and extend along the further air inlet duct.

- Although the invention is illustrated and described herein as embodied in a service ceiling, in particular for laboratories, and a method of installing such a ceiling, it is nevertheless not intended to be limited to the details shown, since various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the claims.
- The construction and method of operation of the invention, however, together with additional objects and advantages thereof will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.
-
FIG. 1 is a schematic three-dimensional representation of an indicated laboratory room having a service ceiling according to the invention; -
FIG. 2 is a schematic cross-sectional view through a service ceiling according to the invention to illustrate different planes in which inlet and exhaust air ducts, along with supply lines, are routed; -
FIG. 3 is a schematic plan view of two service ceilings according to the invention, disposed adjacent to one another, to illustrate an advantageous arrangement of the ducts when there are two or more service ceilings in a laboratory room; and -
FIG. 4 is a schematic three-dimensional representation of a block-like arrangement of T-shaped through-connecting adaptors for connecting the curved intermediate lines. - Referring now to the figures of the drawing in detail and first, particularly, to
FIGS. 1 and 2 thereof, there is shown aservice ceiling 1 according to the invention for routing supply lines in aroom 2 of a building, the room being represented in the figures as a laboratory room with indicated laboratory tables 4 and anaisle 6. The service ceiling contains an intrinsicallyrigid carrier frame 8 composed of profiledmembers 10 which is arranged in a region of aceiling 12 of theroom 2. As can be observed from the representation shown inFIG. 2 , thecarrier frame 8 is accommodated in afirst plane 14 indicated by a broken line, and is supported on theceiling 12 by column-shapedspacers 16 which extend downwardly from the ceiling and which, for example, are fastened to the ceiling using two mountingplates 18 which can be adjusted by screws. The spacers are preferably also configured as profiled members which, in the same way as the remaining profiledmembers 10 of the carrier frame, are provided withslots 20 via which the members can be connected in a known manner by slot nuts (not shown in detail). - As can also be observed from the representations shown in
FIGS. 1 and 2 , at least oneair inlet duct 22 a for feeding in fresh air is disposed in thefirst plane 14, this duct extending above and along theaisle region 6 and its underside extending substantially flush with the underside of the profiledmembers 10 of thecarrier frame 8, as is indicated in detail inFIG. 2 . Theair inlet duct 22 a here preferably has a rectangular cross-sectional shape, and has a height which is preferably equal to or slightly less than the height of the profiledmembers 10 of thecarrier frame 8, with the result that theair inlet duct 22 a—as shown—preferably extends completely in the plane of the carrier frame. - As shown by the representations in
FIGS. 1 and 2 , according to the invention lines 26 for feeding in sanitary media, such as water, air, vacuum, various technical gases and other liquids, and the like, which are customarily required in a laboratory, are disposed above theair inlet duct 22 a in asecond plane 24. Although, to simplify the description, reference is made only tolines 26 for feeding in sanitary media, these can equally also contain lines for discharging the media. - As can also be seen from the representation shown in
FIGS. 1 and 3 , in the preferred embodiment of the invention, in addition to the firstair inlet duct 22 a, at least one furtherair inlet duct 22 b is accommodated within thecarrier frame 8 and extends, in particular, above asecond aisle region 6 b within theplane 14 of thecarrier frame 8. - As can also be observed from the representation shown in
FIG. 1 , thelines 26 for feeding the sanitary media in thesecond plane 24 are preferably routed parallel to one another and in a U shape from the firstair inlet duct 22 a to the furtherair inlet duct 22 b, with the first leg of the “U” extending along the firstair inlet duct 22 a and the second leg of the “U” extending along the furtherair inlet duct 22 b. The lines here are preferably routed in parallel and adjacent to one another, as is represented in detail inFIG. 4 too. - In the
service ceiling 1 according to the invention, electric supply lines and/ordata lines 28 are also preferably routed, at the level of thefirst plane 14, parallel to one another and parallel to the first and secondair inlet duct electrical duct 30 as shown inFIGS. 1 , 2 and 3 preferably being used to route theelectric lines 28. In addition, a correspondingly routedbusbar 38 can also be provided if desired. - The
lines 26 for feeding in the sanitary media and also the electric supply lines routed parallel thereto in thefirst plane 14 situated below them preferably terminate in the region of one of the twoair inlet ducts - As can also be observed from the representation shown in
FIGS. 1 and 2 , furthermore,electric lighting fixtures 32 are preferably likewise provided flush to the underside of the profiledmembers 10 of thecarrier frame 8 in thefirst plane 14, these fixtures being fastened on and displaceable relative to the carrier frame using suitable fastening devices such as slot nuts or the like which engage in theslots 20 of the profiledmembers 10. - The
lines 26 for feeding in the sanitary media preferably have, integrated therein, self-locking T-shaped through-connectingadaptors 34, from which the respective sanitary medium is fed to the individual consumers via curvedintermediate lines 36 which can be plugged onto the through-connectingadaptors 34, as is shown by way of example inFIG. 2 andFIG. 4 . - The through-connecting
adaptors 34 of a plurality of thelines 26 for feeding in the sanitary media are in this case preferably disposed adjacent to one another in the form of a block in two regions of theair inlet duct 22 a and also two regions of theair inlet duct 22 b, as is indicated, for example, inFIG. 1 , in order to provide corresponding central supply points for each carrier frame, for example in four quadrants of a laboratory, from which supply points the sanitary media are routed to the individual consumers via theintermediate lines 36. The consumers may be configured, for example, asmedia columns 40 which are fastened in a displaceable and freely positionable manner at various positions on the profiledmembers 10, in particular in the region above the laboratory tables 4, by way of slot nuts engaging in thelongitudinal slots 20. - As can be observed in particular from the representation shown in
FIG. 4 , the connectingadaptors 34 of a block preferably extend in the direction of theceiling 12 of the room in such a way that theintermediate lines 36 are routed away in the direction of theceiling 12, the space required for this purpose between thelines 26 and theceiling 12 being obtained from the height of anexhaust air duct 42 which extends in thesecond plane 24 preferably on that side of theair inlet duct aisle 6. The advantage obtained as a result is that thelines 26 and also theelectric supply lines 28 and, if appropriate, also the feed lines to thelighting fixtures 32 can in each case be routed in parallel in the form of a “U” in one plane, thus resulting in an optimally structured line routing which allows flexible adaptation to various laboratory arrangements at any time, including retrofitting. This makes it possible for existing laboratories to be reconfigured, expanded or made smaller at some later date with comparatively little effort, since the basic structure of theservice ceiling 1 need not be fundamentally modified, and by virtue of the arrangement according to the invention of the lines and ducts in different planes, it is always possible to have ready access to the lines and connectingadaptors 34. - As can also be seen in
FIGS. 1 and 3 , a plurality of carrier frames 8 can be interconnected adjacent to one another to form a common carrier frame in order to accommodate a multitude of air inlet and exhaust ducts together with runs of supply lines. Here, the cross sections of the adjoining edge members of two neighboring carrier frames 8 are in each case preferably twice as high as wide, with the result that the two members routed in parallel again have a square cross section which makes it possible to line up a plurality ofservice ceilings 1 in the ceiling grid according to the invention. - According to a further embodiment of the invention, recesses 44 are made in the profiled
members 10 of the carrier frame at the level of theair inlet ducts 22 a, through which recesses theair inlet ducts 22 a, preferably along with thecable duct 30 and thebusbar 38, are routed. - According to a further idea on which the invention is based, the operation of installing a
service ceiling 1, which is configured in particular in the above-described manner, involves thecarrier frame 8 first being assembled from the individual profiledmembers 10 in the region of the floor of aroom 2, it being possible for the carrier frame to lie either directly on the floor or to be supported on stands or the like. Next, the air inlet duct orducts air inlets ducts - It is only after all the components have been mounted and the lines have preferably been checked that the
carrier frame 8 together with the components mounted thereon is lifted as a unit with the aid of suitable lifting devices, for example pulley blocks anchored on theceiling 12, and fastened to the ceiling by way of the column-shapedspacers 16, which have likewise already been premounted on theframe 8, and the mountingplates 18. However, as an alternative to mounting by use of the column-shapedspacers 16, there is also the possibility of using a suitable number of support columns to mount thecarrier frame 8 from below at a predetermined distance beneath the ceiling.
